The Allen-Bradley/Rockwell Automation 5094-IB16S safety digital input module has 16 sinking input channels. The module has a backplane power (BP) voltage rating of 15 Volts DC and a maximum backplane power current of 100 milliamps. It has a sensor actuator power (SA) voltage range between 18 and 32 Volts DC and a maximum sensor-actuator power current rating of 1.8 Amps. The 5094-IB16S safety digital input module has a maximum power dissipation rating of 3.5 Watts and a maximum thermal dissipation input rating of 11.94 British Thermal Units (BTU) per hour. In addition to that, the isolation voltage rating of this unit is 250 Volts AC continuous for both the system to field isolation and the basic isolation type, but there is no isolation for the individual input ports or between the sensor-actuator power and input ports.

The Allen-Bradley 5094-IB16S safety digital input module has LED indicators that include 16 red/yellow status indicators, 1 red/green sensor-actuator power indicator, and 1 red/green module status indicator. It has 2 power ports and 2 signal ports for wiring. The size of the signal wire ranges between 0.34 square millimeters and 2.5 square millimeters and it can be stranded or solid copper wire, while the size of the power wire is 2.5 square millimeters and the wire is multi-strand wire.This input module meets the T4 code rating for the North American temperature code, the IECEx temperature code, and the ATEX/IECEx temperature code. The module has approximate dimensions of 87.0 x 94.0 x 54.0 millimeters (3.43 x 3.70 x 2.13 inches) and a weight of 136 grams (0.30 pounds). The 5094-IB16S module operates in non-extreme (non-XT) environments only.
