Input Expansion Unit - 20-03

20-03

The 20-03 is an I/O expander Module which provides four relay outputs, plus eight open drain I/O pins which also serve as inputs.

 

The 20-03 is an I/O expander Module which provides four relay outputs,
plus eight open drain output pins which also serve as inputs.

The 20-03 outputs can be activated by Salcom Relay Protocol or other ASCII text over a serial connection.

Salcom Relay Protocol commands may be embedded in a POCSAG message received by a 20-90 transceiver, allowing activation of outputs by remote POCSAG transmitters.

Activation by POCSAG messages can be limited to a CAP code range, or
outputs can be triggered by any message sent to a CAP code within a range. Outputs may also be configured to respond to any specified text within the serial data.

Inputs on the 20-03 can generate Salcom protocol POCSAG messages over a serial connection which can be transmitted to a pager by a Salcom 20-90 transceiver or a Salcom 20-62 transmitter. Alternatively, inputs can be configured to send any ASCII text over the serial connection in response to an input change.

  • I/O expander for the Salcom 20-62 transmitter or Salcom 20-90 transceiver
  • Bidirectional Point-to-point control over serial or radio link
  • Expandable further by daisy chaining Salcom 20-03 units
  • Four relay outputs with normally open and normally closed contacts
  • Eight bidirectional inputs generate user defined serial messages for rising and/or falling edges
  • Compatible with Salcom message protocol
  • Flexible output activation options
  • Control over Ethernet using third party serial to ethernet adaptors
  • Provides Input and Output capabilities for PC’s, PLC’s, and microcontroller projects
  • Can generate regular watchdog messages to check serial and radio link integrity
Technical Specifications
Power Supply +13.8V typical (11 to 15 VDC range)
Power Consumption Normal Operation: 15mA
Relays: 20mA per energized relay
Configuration Application Salcom Configuration Tool (Sacoto)
