Nittan Evolution Addressable 4-20mA Input/Output Module with Isolator (EV-IO-420)
Product Details for Nittan Evolution Addressable 4-20mA Input/Output Module with Isolator (EV-IO-420)
The Nittan EV-IO-420 is a 4-20mA Input / Output module, with integral –ve line Short circuit isolator compatible with Evolution analogue addressable system devices.
The 4-20mA input can be configured to operate in Sink or Source mode.
The Module includes setting options for a normally closed contact input and Fail Safe mode for Door release requirement.
LEDs are provided to indicate 4-20mA Input, Input & Output active, Fault and Isolator Open.
Device address may be set using EV-AD2-EXT Hand held programmer.
The Short Circuit Isolator will protect the system, whilst allowing the device to continue communication from the opposite side. The isolator will self-reset when the fault clears.
Not compatible with Advanced MxPro4 (Mx4000) Panel. Please use Non-SCI model.
It is not possible to mix +ve and -ve isolator styles on a system.
The following resistors are required for Fault and Alarm monitoring:
- EOL = 10k Ohm
- Alarm = 470 / 680 Ohm
