The 1746-IC16 SLC 500 Sinking DC input Module by Allen-Bradley is a 48V DC sinking module with 16 sinking inputs that uses a Removable Terminal Block (RTB). Its temperature-dependent voltage ranges between 30 and 60V DC sinking at 55°C and between 30 and 55V DC sinking at 60°C. The 1746-IC16 has a backplane draw current of 0.085A at 5V DC and one of 0A at 24V DC. The electrical signal in the input points has a maximum delay time of 4ms for both the ON and the OFF condition. The 1746-IC16 has an OFF-state voltage loss of 10V DC, a current leakage of 1.5mA, and the nominal current on the overall inputs is 4.1mA at a nominal module voltage of 48V DC. It provides a circuit isolation between the backplane and the inputs at 1500V AC tested for 60s and it has a dielectric withstand of 1500V AC. The 1746-IC16’s operating temperature range is between 0 and 60 °C (32 and 140 °F) at 5-95% relative humidity. Its non-operational storage temperature ranges between 40 and 85 °C (-40 and 185 °F). The 1746-IC16 has an operational shock of 30G (3 directional pulses for 11ms) and it can withstand a vibration of 1.0G at 5-200Hz.
