Sensor & Control Port I/O


The Sensor and Control port both have 2 inputs each. Sensor and Control port inputs are auto-sensing for the connected circuit type. Input function as either PNP or NPN. Please note that both sourcing and sinking current will activate the input
Minimum ON current 1.5 mA
Maximum OFF current 0.4 mA


The Control Port output is an NPN transistor whose Emitter (Pin 1) and Collector (Pin 6) are made available to be connected either as sourcing or sinking device in the user’s input circuit
Minimum ON current 2 mA
Maximum ON current 8 mA
OFF current < 100 nA

Sensor & Control Port Power Pins

Pin 5 of all RJ-12 ports provides 24V for powering up a photo-eye or for biasing the output transistor found on the control port. The current that those pins can supply is limited internally. Each side of the module is fused separately and each side’s control port and sensor port share a solid-state fuse rated at 100 mA. For example, If there is one photo-eye plugged into the left sensor port and one photo-eye plugged in the left control port, then the combined consumption of the two photo eyes must not exceed 100mA.

Motor Port

Supported motor types 3 phase BLDC motors with 3 Hall Effect sensors
PWM frequency 10 kHz +/- 0.1%
Maximum starting current 8A
Maximum rated current 5A
Motor Protection* Coil-to-coil short, coil-to-Vcc short, overheating, over-voltage, under-voltage, stall sensing and protection
Brake output type PNP (high side switch)
Brake output current 0.5A (1 A peak)

Motor Ports in Digital IO Mode as Outputs

Motor Coil Pins 3, 4, & 5

In certain modes of operation (PLC I/O and ConveyLogix PLC), Pins 3,4, and 5 can each be independently switched on and off as general purpose digital outputs. Any individual pin can sink up to 1A to ground in these modes, but the total for all 3 pins combined cannot exceed 1.5A. In general purpose I/O mode, these pins cannot source current.

Brake Output Pin 9

As of firmware version 4.19 and later, the brake output pin can be configured through remote PLC to operate as a general purpose output even if an MDR is connected to the port. This situation requires a special cable or break-out board to be used and the MDR in use cannot have and internal mechanical brake, as that mechanical brake requires a connection to pin 9 for proper operation. The brake-output pin 9 is a 24V high side switch (PNP) that can source up to 0.5A continuously and 1A peak.
