I/O Module

The MN-3253 CR adds 32 isolated digital input channels to a Motionnet network, letting you extend remote input capacity without running separate cabling for each signal. Each input port can be configured as NPN or PNP for 12 to 24 V sensors, which simplifies matching the module to the field devices you already use.Cyclic time is 15.1 μs per device at 20 Mbps, and a full line of 64 modules covers 2048 input points within 0.97 ms. Transfer speed is chosen from 2.5, 5, 10 or 20 Mbps using a DIP switch. Input status is updated automatically through the Motionnet system at a constant interval, and you can set interrupts on selected inputs so the controller does not have to poll them repeatedly.The module provides 3000 Vrms input isolation and separates power, communication and I/O for improved protection. Status LEDs show communication state, I/O state and internal 3.3 V power, and a termination resistor switch is provided. Wiring uses 13-pin pluggable terminal blocks, and the plastic housing mounts on a DIN rail. Rated operating range is 0 to +60 °C.ApplicationsMachine automationDistributed digital input expansion for Motionnet systems

MN-3253T CR is a Motionnet expansion module that adds 32 isolated digital input channels to a distributed control network.

Isolation is provided between power, communication and I/O, and an input-change interrupt can be set for chosen points so the host does not need to poll them continuously. Status LEDs show communication state and I/O activity to support commissioning and fault finding.The module uses a plastic housing with pluggable 13-pin terminal blocks and mounts on a DIN rail. It is rated for 0 ~ +60 °C operation and is supplied as the RoHS-compliant terminal block version of the MN-3253 series.ApplicationsMachine automationDistributed digital input expansion on Motionnet systems

MN-3254 CR is a distributed I/O expansion module for Motionnet systems, providing 16 isolated digital input channels and 16 isolated digital output channels in a single DIN-rail housing. Each Motionnet transfer line can carry up to 64 modules, allowing the I/O count to grow to 1024 inputs and 1024 outputs on one network.Timing is deterministic: each device has a cyclic time of 15.1 μs at 20 Mbps, and I/O status is updated automatically over the Motionnet system at a constant interval. Input points can be configured for interrupts, so the controller does not need to poll inputs that are not changing. Each input port can be set to NPN or PNP operation over 12 to 24 V, and the output flywheel diodes can be connected to different supply sources port by port.The CR variant is the RJ-45 connector version listed in the ordering information. Isolation of 3000 Vrms on both the digital inputs and outputs, along with a 1000 V isolated 24 VDC power input, helps separate field wiring from the communication network and the logic supply.ApplicationsMachine automation

The MN-3254T adds 16 isolated digital inputs and 16 isolated digital outputs to a Motionnet network.
