Please note
When connecting inductive or capacitive loads (e.g. load with integrated
switching power supply), an additional power relay with suitable specifi
-
cation must be provided. Each relay output has an integrated 3.15 A fuse
as overcurrent protection.
Typical use of the relay: Enabling contact for external alarm or trigger a
dosing devices or dosing pumps in constant flow applications.
Measurement inputs • 3-electrode sensor (measuring range 0 to max. 20 mg/l, end value
can be set) or membrane sensor
• pH value (measuring range pH 0 to pH14, initial and end value can
be set) or fluoride (measuring range 0 to 20 mg/l)
• Temperature (measuring range 0 to 50°C/32 to 122°F)
Relay outputs • 6x changeover contact with integrated 3.15 A slow-blow fuse
• 5 A, 125/250V AC (contact load capacity of the relays in general use)
• 1/6 HP (122 VA) 125/250V AC
• 5 A, 30V DC (contact load capacity of the relays at resistive load)
• 30W max., 1 A, 30V DC – 0.24 A, 125V DC (inductive load)
• B300
Analog outputs • 4-way mA output module 0/4 to 20 mA (optional)
• Freely configurable signal assignment
• Load max. 500 ohm, accuracy < 0.5 % FS
• Galv. isolated up to 50 V relative to earth
Interfaces • RS485 interface with Wallace & Tiernan protocol for connection to
OPC server, Process Monitoring System or control system for data
visualization
• Ethernet interface (HTTP protocol/Modbus TCP protocol)
• USB interface for firmware update
