The Zelio Logic SR2D201BD is a compact smart relay for standalone control of small machines or building equipment. Expect 12 discrete inputs at 24 V DC (Type 1 per IEC 61131-2) and relay outputs. No onboard display or real-time clock; the unit runs a program memory check at each power-up. Supply voltage is 19.2–30 V DC; pull no more than 100 mA without an expansion module. Cycle time lands between 6–90 ms, which is enough for on/off logic but not fast counting (the discrete input counting frequency is 1 kHz).
