1 / 4 page  MODEL: MDW2A-4R MDW2A-4R SPECIFICATIONS ES-8215 Rev.2 Page 1/4 http://www.m-system.co.jp/ Lightning Surge Protectors for Electronics Equipment M-RESTER LIGHTNING SURGE PROTECTOR FOR RS-485 / RS-422 (life monitor) Functions & Features •Designed specifically for RS-485 or RS-422 transmission line •Life monitor function helps you to decide when you should replace the M-RESTER; reduces maintenance and prevents downtime •LED indicator and alarm contact output indicate the degradation and life span of the surge protection circuits Model ALM PWR 88.5 (3.48) 29.5 (1.16) mm (inch) 124 (4.88) MODEL: MDW2A–4R–[1] ORDERING INFORMATION • Code number: MDW2A-4R-[1] Specify a code from below for [1]. (e.g.MDW2A-4R-M2) [1] POWER INPUT AC Power M2: 100 – 240 V AC (Operational voltage range 85 – 264 V, 47 – 66 Hz) DC Power R: 24 V DC (Operational voltage range 24 V ±10 %, ripple 10 %p-p max.) P: 110 V DC (Operational voltage range 85 – 150 V, ripple 10 %p-p max.) APPLICABLE NETWORK RS-485 or RS-422 conformed network: Modbus, SINNET, MsysNet GENERAL SPECIFICATIONS Construction: Plug-in Connection: M3 screw terminals (torque 0.8 N·m) Screw terminal: Chromated steel Housing material: Flame-resistant resin (black) Alarm indicators PWR: The green LED turns on while the power is supplied. ALM: Tricolor LED (green/amber/red) •Remains off when the power supply is first turned on. •Green: The unit has received one or more surges. •Amber: Replacement is recommended. •Red: The life span has ended. Degradation judged: When the leakage current at the voltage limiter exceed approx. 0.25 mA. Life time judged: When the number of discharges of the discharge element reaches the expected life span. Alarm contact: The N.C. contact is on when the life span of the discharge elements has ended, when the voltage limiter has degraded or when the power supply is removed. Rating: 125 V AC @ 0.5 A (cos ø = 1) 30 V DC @ 1 A (resistive load) Maximum switching voltage: 125 V AC or 110 V DC Maximum switching power: 62.5 VA or 30 W Minimum load: 5 V DC @ 10 mA INSTALLATION Power consumption •AC: Approx. 3 VA at 100 V Approx. 4 VA at 200 V Approx. 5 VA at 240 V •DC: Approx. 2 W Operating temperature: -5 to +55°C (23 to 131°F) Operating humidity: 30 to 90 %RH (non-condensing) Mounting: Surface or DIN rail Weight: 200 g (0.44 lb) |
