What the SR3B262BD brings to the panel
The SR3B262BD is a Zelio Logic smart relay – a compact controller for standalone automation tasks. It packs 16 discrete inputs (24 V DC, Type 1, 4 mA), 6 analogue inputs (0...10 V / 0...24 V, common mode), and 10 transistor outputs (24 V DC, 0.5...0.625 A each). The built-in real-time clock (marked as With) keeps time with a drift of 6 s/month at 77 °F, and the unit runs a program memory check on every power-up – no external watchdog needed. Cycle time runs 6...90 ms, and the logic engine supports counting up to 1 kHz on discrete inputs, plus six analogue channels for sensors or voltage signals. The supply voltage range is 19.2...30 V DC, with a maximum draw of 180 mA when extensions are fitted.
The unit's analogue input repeat accuracy is ±2% at 131 °F, with conversion error ±5% at 77 °F (±6.2% at 131 °F).
