Important note
The products described herein are designed to be components
of a customized machinery safety-oriented control system.
A complete safety-oriented system may include safety sensors, evaluators, signaling units and concepts for ensuring
safe switch-off. It is the responsibility of each manufacturer to
ensure the correct overall functionality of its systems and
machines. ABB, its subsidiaries and affiliates (collectively
“ABB”) are not in a position to guarantee all of the characteristics of a given system or product not designed by
ABB accepts no liability for any recommendation
implied or stated herein. The warranty contained in the contract
of sale by ABB is the sole warranty of ABB. Any statements

Application
The C581 safety relay can be used in EMERGENCY-STOP
devices according to DIN EN ISO 13850 and in safety circuits
according to VDE 0113-1 and/or DIN EN 60204-1, e.g. with
movable guards and protective doors. Depending on the
external circuit, SIL3 according to IEC 61508 or PLe according to EN ISO 13849-1 can be achieved. Depending on the
risk assessment, additional measures may be required in the
sensor circuit (e.g. protected laying of cables). When using
the safety relay in the “Automatic Start” operating mode, the
automatic restart (according to EN 60 204-1, Section 9.2.5.4)
must be prevented through adequate measures in the case of
an emergency switch-off (EMERGENCYSTOP).
Operating mode
The C581 safety relay has three enabling circuits (safe circuits,
NO contacts) and a signaling circuit (not safe, NC contact).
The number of enabling circuits can be completed by adding
one or more C579 expansion modules.
Two LEDs indicate the operating mode of the device.
When the EMERGENCY STOP button or the limit switch is
unlocked and when the ON button is pressed, the internal
circuits of the safety relay and the external contactors are
checked for proper functioning.
Connect the EMERGENCY STOP button or the limit switch
to terminals T1/IN1 and T2/IN2. The ON button is connected
in series with the NC contacts of the external contactor
(feedback loop/circuit at terminals T3/IN3.
