Nittan Evolution EV-IO-420 Single Input and 240v Rated Output Module with 420mA Input

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.

The following resistors are required for Fault and Alarm monitoring:

EOL = 10k Ohm

Alarm = 470 / 680 Ohm
