Hydran* 201i Instruction Manual
Power supply: Separate, isolated, impedance-protected, +15 Vdc
RS485 Local
Network Link
(Isolated)
Standard RS-485 communication port allows daisy-chaining of
up to 32 H201Ci Controllers (H201Ci-C’s and/or H201Ci-1’s) via
the Main Terminal Block
One twisted triad (16 or 18 AWG) with overall shield required
Maximal total daisy-chain length: 1,200 m (4,000 ft)
Standard RS-232 port (DB-9 connector), or standard USB link
(type-B connector)
Allows serial communications with a local host computer (or
remotely with optional modem)
Any H201Ti can be accessed through any H201Ci Controller in
the local network
Run all communication cables in flexible or rigid, metallic
conduits for maximum mechanical and electrical protection
