I-7043 16-ch Non-isolated Sink DO Module, RS-485 DCON Protocol

The I-7042 CR is a 13-channel digital output module for RS-485 networks using the DCON protocol. Each channel uses photocoupler isolation and a sink-type open collector output rated from +3.5 to +50 VDC at 100 mA per channel, with 3750 Vrms intra-module isolation.Power-on and safe output values are programmable, so outputs can be set to a defined state at start-up or when communication is lost. A built-in dual watchdog supports recovery in unattended installations. This blue-cover ordering code suits engineers who need isolated DC switching outputs on a DIN-rail module with a wide operating temperature range of -25 to +75 °C.Compared with the non-isolated I-7043 series, the I-7042 offers channel isolation. The I-7042D variant adds 13 LED indicators for monitoring channel status, which this code does not include.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

I-7042D CR is a DIN-rail remote I/O module that provides 13 digital outputs. Each open collector channel is photocoupler isolated and works in sink mode, so it suits switching NPN-type loads from a 3.5~30 VDC supply, with up to 100 mA per channel.Each output has a front-panel LED, giving a quick visual check of channel status on site. Power-on and safe values are programmable, so outputs can start in a defined state and fall back to a chosen safe state. A built-in dual watchdog supports recovery from faults, and the module offers 3750 Vrms intra-module isolation.Communication is via one RS-485 port using the DCON protocol, with baud rates from 1200 to 115200 bps and selectable data formats. The blue-cover variant is supplied with a 10~30 VDC power input and is rated for -25 ~ +75 °C operation.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

The I-7043D CR is a 16-channel digital output module for RS-485 remote I/O networks. Each channel drives an NPN sink-type open collector output rated for a 10 ~ 30 VDC load at 100 mA per channel, and a status LED for every channel makes it easy to see the output state at the cabinet.Power-on and safe output values are both programmable, so outputs can be set to a defined state when the module starts up or when communication is lost. The module includes a built-in dual watchdog for supervision of the module and the communication link. Because the outputs are non-isolated, the unit suits applications where the isolation requirements are covered elsewhere in the system.Communication uses the DCON protocol over a single RS-485 port with selectable baud rates from 1200 to 115200 bps and several data formats. The module mounts on a DIN rail and operates from -25 ~ +75 °C, which makes it a practical choice for building, factory and machine automation panels.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

M-7043-G CR is a 16-channel digital output module for RS-485 remote I/O networks. Each channel is an open collector sink-type output rated for a load voltage of +10 ~ +30 VDC and 100 mA per channel, so it can switch relays, indicators and other loads without galvanic isolation between channels.The module communicates over a single RS-485 port using Modbus RTU or DCON, selected through configuration software, with baud rates from 1200 to 115200 bps. The power-on value and safe value of the outputs are both programmable, and a built-in dual watchdog supports recovery from communication or module faults. The gray-cover variant (-G) is the model to choose when the housing colour matters. Unlike the M-7043D, this version has no per-channel LED indicators, only a single power and communication status LED.Mounted on a DIN rail and rated from -25 ~ +75 °C, the module suits building, factory and machine automation, as well as remote maintenance, remote diagnosis and test equipment installations.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

The M-7043D-G is a 16-channel digital output module for RS-485 remote I/O networks. Each channel uses an open collector sink-type output rated at +10 ~ +30 VDC and 100 mA per channel, so it can switch loads directly from a common DC supply without galvanic isolation between channels.A LED on each channel shows its output state, which makes commissioning and fault finding quicker at the cabinet. The module communicates over a single RS-485 port with Modbus RTU or DCON, selected through software, and supports baud rates from 1200 to 115200 bps. Power-on values and safe values are both programmable, and a built-in dual watchdog helps the outputs return to a defined state if communication is interrupted.The hardware specification matches the I-7043(D). The gray-cover variant is designed for DIN-rail mounting in a -25 ~ +75 °C operating range.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment
