Description
CROWCON
PT.NO: S01-941
POWER MONITORING MODULE
SUPPLY VOLTAGE: 110-120V 60HZ 3.2A ~
220-240V 50HZ 1.6A
NOMINALLY(24V): 20-30VDC 5A
FEATURES:
MAINS (CONNECTOR): INPUT FROM MAINS SUPPLY, WHEN THE OPTIONAL POWER SUPPLY UNIT IS FITTED. THIS IS RATED AT 29.5V, 150W, WITH INPUT AT 110-120V OR 220 TO 230VAC(SWITCHED), 50-60HZ.
BATTERY (CONNECTOR): CONNECTION TO BACKUP BATTERIES.
GREEN LED: THIS INDICATES THAT THERE IS DC INPUT TO THE POWER MONITOR BOARD, EITHER FROM THE MAINS POWER SUPPLY UNIT OR FROM THE DC INPUT (ITEM B)
24VDC IN (CONNECTOR): IF A 24VDC EXTERNAL POWER SOURCE IS SPECIFIED, THEN THE MAINS POWER SUPPLY UNIT IS NOT FITTED. A 20-30 VDC SUPPLY FUSED AT 5A MUST BE PROVIDED. THE POWER MONITORING MODULE INCLUDES 24V FILTERING. YOU MUST ENSURE THAT THE 24VDC IS SUITABLE FOR USE WITH VORTEX. IF INTERNAL BATTERIES ARE EXPECTED TO BE CHARGED FROM AN EXTERNAL DC SUPPLY THEN THE SUPPLY SHOULD HAVE A MINIMUM VOLTAGE OF 29.0V
24VDC OUT (CONNECTORS): THERE ARE FOUR 500MA ELECTRONICALLY-FUSED OUTPUTS THAT CAN BE USED TO POWER AUXILIARY EQUIPMENT AND CAN BE USED IN CONJUNCTION WITH THE RELAY MODULES TO DRIVE AUDIBLE/VISUAL ALARMS. THESE OUTPUTS ARE 19-29V DEPENDENT ON THE DC INPUT, WITH A 0.6-0.7V DROP. TYPICALLY, THIS IS 28.5V.
RIBBON CABLE CONNECTOR: THIS CONNECTS TO THE NODE CONTROLLER MODULE
The Crowcon S01-941 is a power monitoring module for a gas detection system. It manages the DC supply for the panel from either an optional mains power supply unit or an external 20-30 V DC source fused at 5 A. It connects to backup batteries and links to the node controller module by ribbon cable. It also provides four 500 mA electronically fused 24 V DC outputs for auxiliary equipment, which can work with the relay modules to drive audible and visual alarms. A green LED shows when DC input is present. The module includes 24 V filtering and is offered in used condition.
