Technical specifications
Table 14: CVM03050 Controllers technical specifications
Description
Power Requirement
24 VAC (nominal, 20 VAC minimum/30 VAC maximum), 50/60 Hz, Power Supply Class 2
(North America), Safety Extra-Low Voltage (SELV) (Europe)
Power Consumption
10 VA typical, 14 VA maximum
Note:
The VA rating does not include any power supplied to the peripheral devices
connected to three Outputs (BOs) or Configurable Outputs (COs), which can
consume up to 12 VA for each BO or CO, for a possible total consumption of an
additional 60 VA (maximum). There are 3 BO's and 2 CO's that can each draw 12VA
for a total of 60VA additional power.
Note:
The USB feature is not currently supported.
Power Source
+15 VDC power source terminals provide 35 mA total current. Quantity 1 located in
Universal IN terminals - for active (3-wire) input devices
Ambient Conditions
Operating:
0°C to 50°C (32°F to 122°F) 10% to 90% RH noncondensing
Storage:
-40°C to 70°C (-40°F to 158°F) 5% to 95% RH noncondensing
