To conform to all the latest safety standards (SIL3, IEC 61508, PLe under ISO 13849-1 and EN 574 type IIIC), controls company, ifm electronic, has introduced a new safety relay.
The new G1502S works with all of ifm’s fail safe inductive sensors, but can also be used in a variety of other ways. It performs monitoring tasks in safety applications using different types of electro-sensitive protective equipment (ESPE), so the user doesn’t need a special type of relay for light curtains, e-stops or two hand controls. The latter can be two hand controls to EN 574 type IIIC employing electronic sensors or mechanical switches.
A time delay is an additional feature which is adjustable between 0.25 and ten seconds, which can be applied to two safe outputs. The time delay cannot be tampered with without tripping the relay.
The safety relay has several multi-functional self detecting and self monitoring inputs and short circuit-proof outputs. The simultaneity monitoring of inputs, the functions ‘monitored’ or ‘automatic start’ and two delayed contacts can be selected.
