Modular safety controller does not require programming

The EM-Series is fully modular and does not require programming to help eliminate downtime in case of any unexpected breakdowns. The master control unit (EM1) is a DIN rail-mounting module that features:

• Dual-channel output (13/14, 23/24)
• LED and volt-free contacts for individual indication
• Automatic/manual reset (X1/X2/X3)
• Dual safety channel monitoring
• Power/fault/run indication
• Expandable up to 30 emergency stop switches / non-contact switches / mechanical switches
• TUV approval to CAT4, SIL3, PLe

By means of the ESM expansion module, the EM1 master control unit can operate and monitor up to 30 emergency stop buttons and/or any mechanical device (locking or non-locking). The ESM connects via a six-way strap and draws power from the EM1.

This system has been designed to eliminate fault masking. Wiring each device to a single EM1/ESM will allow for easy identification of faults to maximise production uptime and increase productivity.

'Industry standard' safety relay

For engineers seeking a more traditional product, the SRL1 safety relay has been designed to industry standard specifications to make for easy installation. Featuring dual-channel low-voltage outputs, the SRL1 also has two normally-open control contacts and one normally-closed indication contact. The LED indication increases fault finding capabilities and the 22.5mm DIN rail-mounting design requires minimum control panel space. An automatic/manual monitored selectable switch has been concealed under the lid for easy configuration.

The SRL1 is suitable for use with dual-channel emergency stop buttons or safety devices with two safety outputs, either locking or non-locking types.
