What is SIGA CR?

Description. The SIGA-CR Control Relay Module is an addressable device that provides one Form C dry contact output relay. The relay contacts transfer when the module is activated. The module requires one address on the signaling line circuit (SLC). Addresses are assigned electronically.

What is cr in fire alarm system?

The SIGA-CR/MCR Control Relay Module provides a Form “C”dry relay contact to control external appliances such as door closers,fans, dampers etc. This device does not provide supervision of the state of the relay contact. Instead, the on-board microprocessor ensures that the relay is in the proper ON/OFF state.

What is CR module?

The Control Relay Module and the Polarity Reversal Relay Module are part of the Signature Series system. They are intelligent analog addressable devices available in either plug-in (UIO) versions, or standard 1-gang mount versions.

How do you control a relay module?

Controlling a relay module with the Arduino is as simple as controlling an output – you just need to send HIGH or LOW signals using an Arduino digital pin. With the relay module you can control almost any AC electronics appliances (not just lamps).

How do you use 4 relay modules?

Control 4-Channel Relay Module

1. Bill of materials. Arduino board with USB cable (we use Arduino Uno)
2. Connect wires on relay module. Connect six female pins of wires with relay module male pins as shown on the picture.
3. Connect wires with Arduino.
4. Open Arduino IDE and write code.
5. Upload code to Arduino.

How do you use a relay module?

The connections between the relay module and the Arduino are really simple:

1. GND: goes to ground.
2. IN1: controls the first relay (it will be connected to an Arduino digital pin)
3. IN2: controls the second relay (it should be connected to an Arduino digital pin if you are using this second relay.
4. VCC: goes to 5V.

Where are relay modules used?

Relay modules are used in different applications which include the following.

• Used in over voltage/under voltage protection system.
• Mains Switching.
• Speed control of motors through start-delta converters.
• Automatic electrical appliances.
• Electrical isolation in between high & low power sources.
• Lights.

How does the Edwards/est Siga-CR control relay module work?

The Edwards / EST SIGA-CR Control Relay Module provides a Form “C” dry relay contact to control external appliances such as door closers, fans, dampers etc. This device does not provide supervision of the state of the relay contact. Instead, the on-board microprocessor ensures that the relay is in the proper ON/OFF state.

What is a form “C” dry relay?

The Edwards / EST SIGA-CR Control Relay Module provides a Form “C” dry relay contact to control external appliances such as door closers, fans, dampers etc. This device does not provide supervision of the state of the relay contact.

Will the SIGA-CR work without electrical power?

The SIGA-CR is specifically factory-set with 8 assigned personality codes that configure the SIGA-CR as an output dry relay contact. But in addition, this module will not work without electrical power. There are no reviews yet.
