RELATED PRODUCTS

• Resistor module (model: REM3-250)

Though the REM3 is designed to be mounted directly to this

model, we recommend that it be attached to a separate

terminal board in order to eliminate its heat conduction to

affect the cold junction compensation and the overall

measuring accuracy of this model.

• RZXS configurator software (model: RZMSCFG)

Downloadable at M-System’s web site.

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

Connection

Power input, transmission: Euro type connector terminal

length 7 mm)

RS-232-C: 9-pin D-sub connector (male, lock screw

No. 4-40 UNC)

I/O: M3 screw terminals (torque: 0.6 N·m)

PC Configurator: Miniature jack, RS-232-C level

Screw terminal: Nickel-plated steel

Housing material: Flame-resistant resin (gray)

Isolation: Input 1 to input 2 to input 3 to input 4 to input 5 to

input 6 to input 7 to input 8 to input 9 to input 10 to input

11 to input 12 to trigger input to alarm output to RS-232-C

or RS-485 or configurator jack to power to FG

Zero/span adjustments: Available with PC Configurator

Software for all types of inputs.

Burnout for T/C and RTD input: Upscale, Downscale or No

burnout selectable

Select ‘No Burnout’ to minimize the measuring errors

caused by the sensor/wire resistance and the burnout

sensing current.

With RTD input, the signal may go transiently to the

opposite direction from the burnout setting.

With DC/potentiometer input, the burnout setting is ignored

and the burnout sensing current is cancelled.

In order to specify burnout actions to individual channels,

use PC Configurator Software.

Wire resistance compensation for RTD input: Field

calibration for 3-wire (or 2-wire) RTD available with PC

Configurator Software.

Cold junction compensation (CJC) for T/C input: CJC can be

enabled or disabled. Reference temperature is measured at

the internal sensor by factory setting.

In order to specify cold junction compensation to individual

channels, use PC Configurator Software.

Temperature measured at another channel of this model

can be specified as the reference point by using PC

Configurator Software. This is beneficial to reduce

compensation wires’ cost when there are many temperature

points in remote locations.

Install a relaying terminal board near the sensors and use

ordinary copper wires between the board and this model,

and assign one channel to measure temperature at the

terminal board as the reference.

Operating mode setting: Rotary switch; burnout type, cold

junction compensation, line noise frequency, software filter,

A/D conversion mode, service channel numbers setting
