Need a Specific Revision?

The Omron CS1W-MD291 is a DC Input/Transistor Output Unit with 48 inputs and 48 outputs in a sinking configuration. It boasts high insulation resistance of 20 megohms between external terminals and the GR terminal at 100 V DC, ensuring safety. It offers reliable performance with a dielectric strength of 1,000 V AC between external terminals and the GR terminal for 1 minute at a maximum leakage current of 10 mA. The unit's internal current consumption is capped at 350 mA at 5 V DC. The output specifications feature a rated voltage range of 12 to 24 V DC, with a maximum load current of 0.1 A per point, 1.2 A per common, and 3.6 A per unit. The input specifications operate at a rated voltage of 24 V DC with an input impedance of 4.7 kilo-ohms and approximately 5 mA input current at 24 V DC.
