Features

1. The contacts of the safety relay module are forced to guide, so the monitoring is more effective and safer.
2. The CSRM safety relay module has a slimmer external size and uses plug-in terminals for easy installation.
3. The CSRM safety relay module has 3 normally open, 1 normally closed output and 2 normally open, 1 normally closed output.

CSRMA-two-way normally closed switch monitoring

1.Monitor two normally closed switch signals-emergency stop button, safety door switch, etc.
2.Monitor the short circuit between two signals
3.Monitor any short circuit or short circuit of any single switch, and lock it when the switches are inconsistent.
4, automatic, manual reset adjustable. The 2A1B module can detect the reset button in the manual reset mode and force a single reset. The reset button must be disconnected before the next reset operation can be performed.
5, with external equipment monitoring function, used to monitor the fault status of relays controlling dangerous parts of the machine, such as contact sticking

CSRMB- two transistor signal monitoring

1.Monitor the two transistor signals-photoelectric switches, safety light barriers, etc.
2. With the peripheral circuit, it can also realize the monitoring of two normally closed switching signals.
3. Self-test of the whole circuit, lock when the two signals are inconsistent
4. It has a wider adaptability to the residual voltage of the grating signal. It can still work stably if the residual voltage is greater than 10V.
5. Can monitor NPN and PNP signals, and have stronger adaptability
6, automatic, manual reset adjustable. The 2A1B module can detect the reset button in the manual reset mode and force a single reset. The reset button must be disconnected before the next reset operation can be performed.
7, 2A1B module can achieve suppression function
8, with external equipment monitoring function, used to monitor the fault status of relays controlling dangerous parts of the machine, such as contact sticking

CSRMC-pulse signal monitoring

1.Monitor the output signal of safety light curtain with pulse signal output
2. Narrow band filter design, center frequency 4KHz, effectively avoid false triggering of other interference signals
3. Adapt to Keli Optoelectronics KS02H and KS06 safety light curtains
4. The automatic and manual reset are adjustable. In the manual reset mode, the 2A1B module can detect the reset button and force a single reset. The reset button must be disconnected before the next reset operation can be performed.
5, 2A1B module can achieve suppression function
6, with external device monitoring function, used to monitor the fault status of relays controlling dangerous parts of the machine, such as contact sticking

CSRMD-Two-handed button monitoring

1.Monitor the button signal of both hands
2. Button signal consistency detection, when the trigger time difference between the two-hand button is greater than 0.5S, it is regarded as invalid trigger.
3. Independent dual loop operation, full loop self-check, lock when the two signals are inconsistent
4, 2A1B module can realize the monitoring function of external equipment, used to monitor the fault status of relays controlling dangerous parts of the machine, such as contact sticking
