Functions & Features
SPECIFICATIONS OF OPTION: Q (multiple selections)
COATING (For the detail, refer to M-System's web site.)
/C01: Silicone coating
• Loop-powered design eliminates output loop power supply
• 500 V DC input-to-output isolation
• 350 Ω output drive with 4 – 20 mA
/C02: Polyurethane coating
/C03: Rubber coating
Typical Applications
TERMINAL SCREW MATERIAL
/S01: Stainless steel
• Isolation between control room and field instrumentation,
between telemetering system and input device
• Eliminates ground problems in existing systems thanks to
easiness of application without requiring additional power
wiring
GENERAL SPECIFICATIONS
Construction: Stand-alone; terminal access at the front
Connection: M4 screw terminals (torque 1.2 N·m)
