Electrical Ratings

Maximum Ratings

!Operating outside these parameters may result in permanent failure or unexpected device behavior

*This is the maximum current that will be allowed by the hardware over current protection circuitry. On board firmware limits the amount of current based on the quantity and motor types connected

Certifications & Standards

Sensor & Control Port I/O

Inputs

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

Outputs

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

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.

!Current in excess of 100mA drawn from the sensor port’s 24V pin may cause permanent damage to the sensor detection circuit. Care should be taken to avoid excess loads, short circuits and miss-wiring of the sensor port

Motor Port

!*During normal operation as an MDR port, the internal protection circuitry is not capable of detecting a short-circuit between a BLDC coil output and ground. Such a short-circuit will cause damage to the high-side bridge transistors. When operating these outputs as general purpose outputs, the high-side transistors are disabled, so a pin-to-ground short-circuit is not an issue

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.
