Remote I/O module, Digital signals, Output, Relay - UR20-4RO-CO-255

The Weidmüller UR20-4RO-CO-255 is a 4-channel relay output module (RO = relay output, CO = changeover contact) that clips onto a u-remote station behind the fieldbus coupler. Unlike the transistor UR20-xDO-P modules it switches volt-free changeover contacts up to 255 V and 6 A, so it is the variant to use for mains-voltage loads or where the load circuit must stay isolated from the 24 V system.

• Channels: 4 relay outputs, changeover (CO) contacts
• Switching voltage: 255 V AC / 255 V DC (UL: 277 V AC)
• Switching current: 6 A per channel, 24 A total per module
• Switching frequency: max. 5 Hz
• Response time: 20 ms
• Connection: PUSH IN, 0.14–1.5 mm²
• Diagnostics: module level (no per-channel diagnosis)
• Module width: 11.5 mm
• Operating temperature: −20 °C to +60 °C
