R/T87000 PRODUCT OVERVIEW





Compact 4-wire system (separate power supply) design allows simple wall or rail mounting. Choice of current and / or voltage outputs.Power options include Isolation to prevent ground loops and associated problems. Optional SPDT relay allows unit to provide Alarm Function. RTD (Pt100) units are completely linearized.



R/T87000 features
• 4-wire rail- / wallmount transmitter
• Analogue transmitter
• Available for Pt100 (RTD) or thermocouple K,J,T  or E input
• High accuracy (typical 0.1%)
• Temperature linear output (Pt100 version)
• Voltage linear output (T/C version)
• Choice of current & voltage outputs
• 5 Year warranty
