That 5 A figure is the thermal continuous current — it's the number that matters when you're switching heaters, solenoids, or contactor coils in a panel. ## What it takes to slot it in It occupies one slot out of eight on the TB16SC or TB16 IM-SC terminal block — the usable terminal block is specifically the TB16SC. The module is 10 mm wide, 64 mm tall, and 51 mm deep, so it fits the standard SIMATIC SC slice profile without stealing extra DIN rail space. The relay coil runs on 24 VDC, same as the backplane supply, and draws a max of 15 mA from the L+ rail. Reverse polarity protection is built in, and there's a green LED status indicator per output for quick visual checks on the cabinet floor. ## Isolation that separates channels from trouble Galvanic isolation between the channels and the backplane bus is listed, and between the channels and the relay power supply as well. The isolation between the internal M or relay supply and the outputs is rated 2500 V DC, while between M internally and the relay supply it's 1500 V AC — numbers that matter when you're keeping field wiring faults off the backplane.","metaTitle":"Siemens 6ES7122-1HA01-0AA0 SIMATIC SC 1DO Relay, 5A","metaDescription":"Siemens 6ES7122-1HA01-0AA0 SIMATIC SC electronic submodule, 1 digital output relay rated 5A resistive, 24 VDC coil.
