Sens-485-UI connect two analog current or voltage inputs to the Poseidon unit throught RS-485 bus. DIN rail mounting, galvanic separated analog signals, both channels can be configured to measure voltage 0..15V or current 0..25mA.
 The Sens-485-UI converter communicates via RS-485 using ASCII protocol, which is compatible with Poseidon family products. The converter applies two addresses of two letters (for example „A“/“a“) except the letter „T“ (see manual).
First channel represents the address with capital letter (for example „A“), the second channel represents the address with small letter (for example „a“). Both addresses are assigned simultaneously with the capital letter assigning.

The converter mounting
The converter is designed for mounting on the DIN bar 35 mm. Push in the top end and use a flat-head screwdriver to unfasten the pawl. Push the low end in the bar direction to lock. To Dismount follow the instruction backwards.
Connecting to Poseidon devices
 Sens-485-UI unit can be connected to the Poseidon family devices with RS-485 bus (Industrial Bus). To connect over RJ45 connector and TP cabling, use these scheme.
Communication protocol
The sensors works in request-response mode. Maximum response time on the line is 20ms.
- Communication bus: RS-485
- Range of addresses: “A/a” .. “Z/z” (except „T/t“) (25 addresses)
- Communication: ASCII, see datasheet
- Response time: max. 20 ms to command
- Baudrate: 9600 baud
- Number od data bits: 8
- Parity: no
- Number of stopbits: 1
Detailed description of communication protocol is available in Product list.
Sens-UI Poseidon support
 After connecting to Poseidon model 1250 unit, data measured in Sens-UI unit is available on local network or via internet in Your web browser.
The values are accessible via following protocols:
- Modbus/TCP
- SNMP
- XML
- Email warning on value out of safe range
- SNMP trap warning on value out of safe range
