  • Standard rack (model: 38N-BY1, -BH1) GENERAL SPECIFICATIONS Construction: Rack mounted; terminal access via screw terminals at the front and via card-edge con- nector at the rear Connection: M3.5 screw terminals and card-edge connec - tor Screw terminal material: Nickel-plated steel (torque 0.8 N·m) Power input: Supplied via card-edge connector Fuse for voltage output: 0.5A incorporated Alarm: Dry contact output at the rack terminal when the fuse is blown. Isolation: DCS output or external contact or power to power for voltage output or fuse alarm output Indicator LED: Orange light turns on with the output ON INPUT ■ DCS OUTPUT: Open collector Coil rating: 24V DC @10mA (approx.) ■ EXTERNAL CONTACT (EM valve control SW): Dry contact Coil rating: 24V DC @20mA (approx.) OUTPUT ■ VOLTAGE CONTACT OUTPUT Rated load: 100V AC @0.5A (cosø=1) 30V DC @0.5A (resistive load) Electrical life 10 5 cycles (rate 30/min.) Maximum switching voltage: 125V AC or 30V DC Maximum switching power: 50VA or 15W Minimum load: 5V DC @10mA Mechanical life: 5 × 107 cycles External protection: Contact protection and noise quench- ing recommended when driving an inductive load (coil, etc.) ■ FUSE ALARM OUTPUT: Dry contact Rated load: 50V AC @0.5A (cosø=1) 30V DC @0.5A (resistive load) Electrical life 10 5 cycles (rate 30/min.) Maximum switching voltage: 50V AC or 30V DC Maximum switching power: 25VA or 15W Minimum load: 5V DC @10mA Mechanical life: 5 × 107 cycles External protection: Contact protection and noise quench- ing recommended when driving an inductive load (coil, etc.) INSTALLATION Power input: Operational voltage range 24V DC ±10%, ripple 10% p-p max., approx. 40mA Operating temperature: -5 to +55°C (23 to 131°F) Operating humidity: 30 to 90% RH (non-condensing) Dimensions: W23×H149×D102 mm (0.91”×5.87”×4.02”) Weight: 150 g (0.33 lbs) PERFORMANCE Insulation resistance: ≥100MΩ with 500V DC (DCS output or external contact or power to power for voltage output to fuse alarm output) Dielectric strength: 1000V AC @1 minute (DCS output or external contact or power to power for volt- age output to fuse alarm output) DESCRIPTIONS The 38N-4 is a DCS-front-end use relay card installed in a dedicated 19-inch rack, used to manually turn on/off a volt- age contact output to directly drive devices such like elec- tromagnetic valve, and to automatically turn it off by an external status contact from the DCS.
  • Voltage output (LED turns on at output)
  • Test switch useful for the DCS test running
  • 0.5A fuse for the voltage output
