Honeywell DIN Controller and Indicator

Product Description

Product Details :

Four voltage levels of input and output wiring may be used with the unit :

• Analogue input or output (for example thermocouple, RTD, VDC, mVDC or mADC)
• Relays & Triac outputs
• SSR Driver outputs
• AC power

Limitations :

• Honeywell shall not be liable for any incidental damages, consequential damages, special damages, or any other damages, costs or expenses excepting only the cost or expense of repair or replacement as described above
• Products must be installed and maintained in accordance with these instructions
• There is no warranty against damage to the product resulting from corrosion
• Users are responsible for the suitability of the products to their application
• For a valid warranty claim, the product must be returned carriage paid to the supplier within the warranty period
• The product must be properly packaged to avoid damage from Electrostatic Discharge or other forms of harm during transit
• These instruments are microprocessor based process controllers, indicators, and limit controllers
• They can measure, display or control process variables such as temperature, pressure, flow and level from a variety of inputs
• EEPROM technology protects against data or configuration loss during power outages
• Inputs are user configurable for connection to thermocouple and RTD probes, as well as

Use of Shielded Cable:

• All analogue signals must use shielded cable
• This will help eliminate electrical noise induction on the wires
• Connection lead length must be kept as short as possible keeping the wires protected by the shielding
• The shield should be grounded at one end only
• The preferred grounding location is at the sensor, transmitter or transducer

Noise Suppression at Source:

• Usually when good wiring practices are followed, no further noise protection is necessary
• Sometimes in severe electrical environments, the amount of noise is so great that it has to be suppressed at source
• Many manufacturers of relays, contactors etc supply surge suppressors which mount on the noise source
• For those devices that do not have surge suppressors supplied, Resistance-Capacitance (RC) networks and/or Metal Oxide Varistors (MOV) may be added

Inductive coils :

• MOVs are recommended for transient suppression in inductive coils, connected in parallel and as close as possible to the coil
• Additional protection may be provided by adding an RC network across the MOV
