Application Scenarios
l Differential input: ±50 V common-mode rejection — steel-mill VFD noise immunity
l 14-bit + sign: 0.015 % F.S. — custody-transfer class accuracy
l 2.5 kV isolation: channel-to-channel & channel-to-bus — SIL2/SIL3 safety loops
l Hot-swap: key-switch confirm, <200 ms break — zero downtime maintenance
l One module, multiple ranges: voltage & current jumper-select — no external resistor bank
