Safety Technique
SAFEMASTER C
Multifunctional Safety Module
UG 6970

Product Description

The multifunctional safety module UG 6970 provides protection of men
and machines by enabling and disabling a safety circuit. It is used together
with e-stop buttons, safety gates, light curtains with self testing (type 4)
to IEC/EN 61496-1, 2-hand buttons on presses for metal processing and
productions machines with dangerous closing movements (type III C to
EN 574) and safety mats, edges and tape switches. Simply select 2 out of
6 safety functions on rotary switches - ready. This reduces divers types of
safety modules in stock and simplifies your disposition.

Approvals and Markings

Application

For enable and interrupt a safety circuit in a safe way. It can be used to
protect people and machines in applications with e-stop buttons, safe-
ty gates, light curtains with selftesting (Type 4) acc. to IEC/EN 61496-1,
2-hand controls for presses as well as other production machinery with
dangerous closing action (Type III C to EN 574) and for safety mats, safety
edges and tape switches with a max. switching current of 15 mA.
