Conformity/Approvals
Conforming to standards
Other approvals:
Note 1: The system operates directly from 24 VDC ±20%. Power to the system must come from a
24VDC SELV power supply which meets the voltage interruptions and dip requirements of IEC 61496-1
(per section 4.3.2.2 and 5.4.3.2) and IEC 60204-1 (per section 4.3.3), Omron STI part number 42992 or
equivalent. The power supply size is dependent on the total current required by two solid-state safety
outputs and the auxiliary output should not exceed 1.35 A. Total system current requirements is the sum
of transmitter (285mA), receiver (450mA), OSSD1 (625mA), OSSD2 (625mA).
Note 2: 24 VDC is nominal. Actual voltage is dependent upon supply, V = Vsupply - 1V.
Note 3: When using a Omron STI-supplied 30 meter receiver cable the total load current is limited to
1.2A at 24V (nominal). See when using customer supplied cables.
