5.5.4 24 V DC supply via SIOX terminals 93 and 94
In addition to the maximum four SIOX Extension Modules the CI 3000 Store Computer can supply 24 V DC
power to other external loads. This power can be taken from terminals 93 (-) and 94 (+) on the SIOX Extension
Module.
Danger of failure of alarm messaging! A short circuit on the terminals 91-95 (SIOX-SUPPLY)
leads to the failure of the CI 3000 store computer for the duration of the short circuit, and conse
quently the failure of the alarm messaging!
It is possible to power further external 24 V DC consumers (CAN bus repeater etc.) in addition to the
S0 interfaces however this is not recommended!
In the event that consumers are to be supplied via the terminals 93 (-) and 94 (+), then the maximum permissi
ble summation current must be calculated, taking in to consideration the following factors.
S Max. total 24 V DC power supply of CI 3000 Store Computer: 24V DC / 600 mA
S Current each SIOX Extension Modules for 8 relay outputs (24 V DC) 96 mA
Current each relay output 12 mA
S Tolerance factor 80%
Max. total current [mA] = (600 mA - (No. of SIOX relay outputs * 12 mA)) * 0.8
If other loads to be supplied with power via terminals 93 (-) and 94 (+), the maximum allowable total current of
all SIOX Extension Modules must be determined with consideration to the following conditions:
No. of SIOX
Extension
Modules
No. of
relay
outputs
Current each SIOX Tolerance factor 80% Max. allowable
total current on all terminals 93 (-)
/ 94 (+)
1. SIOX max. 8 8 * 12 mA = 96 mA (600 mA - 96 mA) * 0,8 400 mA
2. SIOX max. 16 16 * 12 mA = 192 mA (600 mA - 192 mA) * 0,8 320 mA
3. SIOX max. 24 24 * 12 mA = 288 mA (600 mA - 288 mA) * 0,8 250 mA
4. SIOX max. 32 32 * 12 mA = 384 mA (600 mA - 384 mA) * 0,8 170 mA
