Specification

Inputs are ON with +10 Vdc to +30 Vdc applied and OFF when less than +1.5 Vdc or 0.2 mA is applied. Input current at 24 Vdc is 4.8 mA and input resistance is about 4.8k ohms.

Maximum load on each output channel is 150 mA with 3.5 Vdc max voltage drop from I/O supply + to output. Outputs are rugged and require no freewheeling diode on inductive loads. Outputs are short-circuit proof to ground (0 V) or any voltage from 0V to the I/O power supply voltage.

Optical isolation for I/O is functional only and does not provide safety rated isolation. I/O circuits must be PELV for any extra low voltage circuits to be PELV. For UL installations, I/O wiring must be from a limited voltage/limited energy or limited voltage.limited current supply.

Figure 26: Epsilon EP-B Input/Output Wiring Diagram

As part of PELV wiring, I/O circuits are intended to be used within a zone of equipotential bonding where cables or wiring would typically be no more than 10 ft [3 m] long. These circuits have not been evaluated for EMC immunity which would be required for longer cables.

I/O Connector (J3) Functions

The I/O connector is a 26-pin male high-density dsub connector on the front of the drive. A low profile standard terminal interface board (STI-24IO) and cable assembly (EIO26-xxx) are available for making connections convenient. Figure 26 shows pin-outs for I/O channels supported in the EP-B drive and for external wiring typical of all I/O channels. Figure 27 shows pin-outs for EP-I and EP-P models. Input channels 1-8 have high speed capture capability in the EP-P models. Figure 28 shows the STI-24IO interface board for discrete wiring to I/O.
