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: 0.6N·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 trigger input to alarm output

to RS-232-C or RS-485 or configurator jack to power to FG

Burnout: Upscale, downscale or no burnout selectable with

the operating mode setting rotary switch (default: No). Set

to ‘No Burnout’ when other devices are connected in

parallel to the R1MS.

Operating mode setting: Rotary switch; burnout type and

line noise frequency setting

Line noise filtering: Specifying line frequency to 50 Hz or 60

Hz in order to increase normal mode noise rejection ratio.
