Analog Inputs Hardware Overview • 1-7
• 100K Cycles
• Pin 17 is common for relays 1 & 2
• Pin 24 is common for relays 3 & 4
• Relay 1 (RL 1) - Pin 15 NC / Pin 16 NO
• Relay 2 (RL 2) - Pin 18 NC / Pin 19 NO
• Relay 3 (RL 3) - Pin 20 NC / Pin 21 NO
• Relay 4 (RL 4) - Pin 22 NC / Pin 23 NO
1.9 Analog Inputs
• Supports 0-10VDC, 0-1 DC, 0-5VDC, 2-20mA, 4-20mA, Emerson NTC temperature and dry contact digital input.
• Supports engineering units for temperature, pressure, humidity, light level and generic percentage.
• When wiring transducers or amplifiers (for example, outdoor light level) the odd numbered terminal is the + or sig-
nal and the even numbered terminal is the – or common.
• Provides (2) 12VDC (160mA) and (2) 5VDC (40mA) power supply terminals for humidity sensors, pressure
transducers, and more.
NOTE: General purpose relays are cost-
effective 5-15 Amp switching devices used in a
wide variety of applications.
Features:
• Electrical loads of 5 to 15 Amps.
• Contact configurations through 3PDT.
• Coils molded in polyester for environmental
protection.
