Parameters Parameter Specification Product Range Modicon TM3 Modular I/O System Module Type Relay Output Module Commercial Reference TM3DM32R Number of Channels 32 Contact Type SPDT (Single Pole, Double Throw) - Form C (1 Normally Open, 1 Normally Closed) per channel. Maximum Switching Voltage 250 V AC / 30 V DC Maximum Switching Current 2 A per channel (resistive load @ 30°C). Derating required for inductive loads. Maximum Inrush Current Lamp: 10 A for 20 ms. Inductive (L/R=7ms): 15 A for 20 ms. Minimum Switching Current 10 mA at 5 V DC (to ensure contact wetting). Contact Life Mechanical: ≥ 10 million operations. Electrical: Depends on load (e.g., 100,000 ops @ 2A 250V AC resistive). Initial Contact Resistance ≤ 100 mΩ Operate/Release Time ≤ 10 ms typical Isolation 1500 V AC between coil and contacts. 1000 V AC between open contacts of different channels. 500 V AC between field side and bus side. Connection Removable screw terminal block (two terminals per channel for NO and NC contacts). Diagnostic LEDs Green LED per channel (indicates relay coil energization). Module I/O LED (indicates power and communication status). Bus Interface TM3 bus via connection to a TM3 base module (e.g., TM3XB). Power Consumption From 5V bus: 140 mA (typical). From 24V field supply for coil: 5 mA per active channel (typical). Operating Temperature -20°C to +60°C Storage Temperature -25°C to +70°C Relative Humidity 10% to 95% (non-condensing) Standards & Certifications CE, UL, cUL, RoHS compliant.
