A dedicated cable is required to connect the module to the

PC. Please refer to the internet software download site or

the users manual for the PC configurator for applicable

cable types.

GENERAL SPECIFICATIONS

Construction: Plug-in

Connection: M3.5 screw terminals

Screw terminal: Chromated steel (standard) or stainless

steel

Housing material: Flame-resistant resin (black)

Switching: Programming I/O specifications

Isolation: Input to DC output to alarm output to power

Overrange output: Approx. -15 to +115 % at 1 – 5 V

Burnout protection: for T/C or RTD inputs; upscale standard;

downscale optional (Choose an output range with

suppressed zero [e.g. 1 – 5 V, 4 – 20 mA] for downscale

butnout.)

Linearization: 100 points max.

Cold junction compensation (T/C): CJC sensor (included) to

be attached to the input terminals

Status indicator LED: Red LED

Alarm monitor LED: Red LEDs turn on when coils are

energized.

Programming: Programming Unit (model: PU-2x); input type

and range, zero and span,

DC output range, simulated output; relay trip action,

setpoint and deadband (hysteresis), failsafe relay trip, ON

delay time, power ON delay time, inverted output,

linearization and burnout.

Hardware setting with front DIP switches must be done

before software programming.

(Refer to the users manual of JXCON for the adjustments

configurable with JXCON.)
