I-8055W-G 8-ch Non-isolated DI/DO Module, Dry Contact Input & Sink NPN Output

I-8055 CR is a PAC I/O module that combines 8 non-isolated digital input channels and 8 non-isolated digital output channels in one unit. The inputs are designed for dry contact connections, where a switch or relay contact to GND sets the channel ON and an open contact sets it OFF. The outputs are sink-type open collector channels that switch to ground with a load voltage of +5 VDC to +30 VDC and up to 100 mA per channel.Each channel status can be checked visually, as the module carries 16 LED indicators for the I/O channels, plus a power and communication indicator. Each terminal is rated for ±4 kV ESD protection (IEC 61000-4-2) as standard, which helps the module tolerate electrostatic discharge during installation and service.The blue cover version (CR ordering code) is the variant offered here. The module suits machine and building control cabinets where a compact, low-profile I/O block with simple contact inputs and sink outputs is needed. Power consumption is 1 W maximum, and the unit is rated for operation from -25 to +75 °C.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

The I-8055-G is a digital I/O module from the I-8K/I-87K low-profile series, combining eight dry contact inputs with eight sink-type outputs on a single unit. It suits engineers who need straightforward switching and sensing signals in automation panels without galvanic isolation between channels.Each input channel is activated by connecting it to GND and reads as open when released, so standard switches, relay contacts and push-buttons can be wired directly. The outputs are open-collector, sink-type (NPN) channels rated from +5 VDC to +30 VDC at 100 mA per channel, and 16 LED indicators show the state of the I/O channels together with power and communication status.The module is suited to building, factory and machine automation as well as remote maintenance, remote diagnosis and test equipment. The grey cover identifies the -G variant, and 4 kV ESD protection is provided on every input and output channel.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

The I-8050W-G CR provides 16 universal digital channels, each of which can be programmed as either a digital input or a digital output. This makes it a flexible choice where the I/O mix may change or is not fixed at the design stage.Every channel is photocoupler isolated. Inputs are sink-type with a +10 ~ +30 VDC ON level, and outputs are isolated open-collector sink drivers rated for a +5 ~ +30 VDC load at 100 mA per channel, with short-circuit protection. Power-on and safe values can be configured for the outputs.16 channels, each programmable as input or output3750 VDC intramodule isolation as standard±4 kV ESD protection on each terminalCE, FCC, RoHS and WEEE listedApplicationsInterfacing sink-type field switches and sensors to a controllerSwitching loads of up to 100 mA per channel with open-collector outputs in industrial control panels

The I-8051 CR is a 16-channel digital input module for reading dry contact switches over long cable runs. Each channel is read by connecting it to GND (ON) or leaving it open (OFF), so it suits simple switch, relay and push-button monitoring in panel and machine wiring.All 16 channels are non-isolated and each terminal has ±4 kV contact ESD protection to IEC 61000-4-2. A status LED for every input, plus one for power and communication, makes it straightforward to check field wiring and channel state during commissioning and fault finding.This variant is the blue-cover version. The I-8051-G is listed as a similar model in the same series.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
