When your SIMATIC safety system needs to branch out, add this failsafe digital I/O module from Siemens. It's fitted with four outputs, so you can use it to control devices such as motors, actuators and alarms. Signals are controllable with PROFIsafe, enabling the reliable transmission of safety messages in emergency situations. Integrated short-circuit protection stops electrical faults in their tracks. The module's designed to meet international standards for programmable safety systems, so you can be sure it works when you need it to. Use it on automated production lines and in heavy plant environments to safeguard people and machines.

• Dimensions of 100 (L) x 70 (W) x 75mm (D) keep it compact
• Lift-up flaps on the front give you easy access to the terminals
• Diagnostic and status LEDs for speedy troubleshooting
• Yellow markings on housing mean you can easily identify it as a safety module

You can combine this digital I/O module with other devices in the SIMATIC ET 200S range to build a bespoke safety system. These include digital input (203-4077), analogue input (203-4054) and relay output (203-4075) modules.
