HNL INSTRUMENTS & CONTROLS
800 series specifications

Standard Electrical Smartstats:
Power Supply
24Vdc @ 3.5mA without 4 - 20mA transmission.
24Vdc @ 30mA with 4 - 20mA transmission.
Maximum supply voltage 30Vdc.

Switching
Relays have multi-layered contacts making them suitable for switching from 100mVdc 100µA to 30Vdc 3A or 250Vac 4A.
Minimum switching life 100,000 operations.

I.S. Certified Smartstats:
EExia IIC T4/T5/T6 BS5501: Parts 1 & 7, EN50 014 & EN50 020. T4 = 80°C, T5 = 55°C, T6 = 40°C. Certificate No. Ex94C2199.

Power Supply
24Vdc @ 3.5mA without 4 - 20mA transmission.
24Vdc @ 30mA with 4 - 20mA transmission.
24Vdc supply via any 28V 300ohm I.S. source certified by Baseefa or any EEC approved certification body to EEx ia IIC.
For Smartstat supply C=0, L=0.
Suitable barriers include MTL702+, MTL3041, MTL5041 etc.

Switching
Each relay must be connected to a separate (or the same) I.S. source certified by Baseefa or any EEC approved certification body to EEx ia IIC whose output does not exceed 28Vdc.
Umax IN = 28Vdc, Imax IN=3.33A. For relay outputs C=0, L=0.
Suitable barriers include MTL707+, MTL2210B, MTL5016 etc.

All Smartstats:
Accuracy
Linearity Error: +/- 0.1% typical, +/-0.25% max.
Pressure hysteresis: +/- 0.1% max.
Temperature coefficient: 0.01% per °C typical, 0.025% max.
