2.3.1 Output Card Specifications
2.3.1.3 Relay Output Card
Number of Outputs: 4
Relay Rating: Capable of switching
Either:
0.5A at 12V DC
Or:
0.5A at 24V AC
Higher power relays can be driven from the card where necessary
Pin Out: See Table 6 – Output Card Wiring
Other Notes: Normally open or normally closed are available as standard.
2.3.1.4 Analogue Output Card
Number of Outputs:
4
Output Options: Either:
A Voltage between 2 <<?? – SOME REFS STATE 0 HERE>> and 10V
(1mA)
Or:
A Current between 0 and 20mA (compliance = 12V)
Pin Out: See Table 6 – Output Card Wiring
Other Notes: GND is internally connected to PE
On a motorised valve system using the voltage output, contractors
must ensure that the power to the drive Control Unit (commonly 24V
AC) is connected appropriately to avoid earth conflicts.
Fault conditions are indicated by a permanent drop to zero and a low
battery condition is indicated by a brief drop to zero.
Analogue cards are available with 8 or 12 bit resolution
