I’d like to ask what the difference is between IOP32 and IOPHC32.
Thread Content
They are all surge protectors, but there must be some differences, right? I couldn’t find any differences by searching on Baidu online, so I came here to ask for help.
IOP32 provides surge protection for one loop or 2 wires. IOP HC32 offers surge protection for one high-current loop, up to 5A; it is designed for high-current circuits with a maximum current of 5A. Instrument control systems involve low-voltage electricity, so this is generally not needed.
What does “2 wires” in the statement “IOP32 provides surge protection for one loop or 2 wires” refer to? It can’t be a two-wire system, right?
IOP32 provides surge protection for one loop or 2 wires. IOP HC32 offers surge protection for one high-current loop, up to 5A; it is designed for high-current circuits with a maximum current of 5A. For instrument control and power supply, IOP HC32 is generally used. For some instruments, if IOP32 is used, the instrument’s current limitation may cause abnormalities; IOP32 is typically used with 4-20 mA 2-wire analog instruments such as temperature and pressure transmitters. IOP32 is single-channel, while IOP32 D is dual-channel
