Relais Extension8

Relais Extension 8

  • ITEC relay extension is an 8-fold relay card and serves as a module for an extension of the digital outputs.
  • For connection to a Spider04/44 or SpiderLine16 unit another 8 outputs (switched via relays) can be added to the available 8 outputs with a suitable configuration.
  • The relay card comprises eight relays with a changeover contact and is controlled via a serial interface. Connection is realised with a 9-pole null-modem cable.
  • The maximum admissible switching current is 7A for reach relay.
  • The admissible Supply voltage is 12V/DC min., 24V/DC max.

CONNECTION TO RS232 CONNECTOR

For RS232 operation, jumpers JP2 and JP3 must be inserted in position 1-2.
JP1 must be inserted in position 1-2. Connection to the Spider is done via a
9-pole null-modem cable; alternatively, the control lines can be connected
directly to RXa, Txa and GND:

RXa = data from the Spider to the relay card
TXa = return line to the Spider
GND = ground

The RS232 cable to the Spider unit must not be longer than 3m

CONNECTION OF EXTERNAL ASSEMBLIES

One external circuit can be switched with each of the eight relays.
Relay capacity 24V/AC, 7A or 24V/DC, 7A

NO = normally open contact
NC = normally closed contact
C = common connection
