The language of the display is switched by simultaneously pressing the START and STOP buttons during switch-on. The function generator provides five operating modes: counting pulses, measuring frequencies, measuring times, outputting square wave signal and outputting DC voltage. – Operating voltage: 24 V DC – Voltage of the input signals: +15 – +28 V DC – Timing range: 0000 - 9999 ms – Frequency measurement range: 0.1 - 1000 Hz – Frequency output: 24 V, max. 2 A, 0.01 - 200 Hz – Pulse width modulated output: 0 - 24 V DC, max. 2 A – Electrical connection: Sockets for 4 mm safety plug Order no. 544315 2 Operational status display For the easy connection and indication of different operating modes and states by flashing and continuous signals of different colors. Three LED light elements (green, yellow, red), each with a socket for continuous light and flashing light, operating voltage sockets each 6x 24 V DC and 0 V, all connections designed for 4 mm safety plugs, fastening via contact protection with integrated detenting handle strip in the ER mounting frame for electrical connection and control units. Order no. 567263 3 4 3 Mushroom-head safety switch With dual-circuit switch-off and self-monitoring, can be removed. The two NC contacts open when the mushroom-head safety switch is actuated. A further NO contact is actuated when the safety switch is plugged in and opens when the mushroom-head safety switch is removed or manipulated. Supply voltage sockets each 6x 24 V DC and 0 V, all connections are designed for 4 mm safety plugs, fastening via contact protection with integrated detenting handle strip in the ER mounting frame for electrical connection and control units. Order no. 567261 4 Safety relay for emergency stop and safety door With 4 positively driven relay outputs and 2 input channels, can be used as a safety gate monitor or as emergency stop monitoring. – Operating modes: start-up test, cross-circuit detection, self-test, automatic start, single-channel, manual start, manual start with monitoring, without cross-circuit detection, dual-channel – 3 safety contacts (N/O), non-delayed – 1 auxiliary contact (N/C contact), non-delayed – 1 semiconductor output – Operating voltage: 24 V DC – Operating voltage sockets each 6x 24 V DC and 0 V, all connections designed for 4 mm safety plugs, fastening via contact protection with integrated detenting handle strip in the ER mounting frame for electrical connection and control units. Order no. 567262
