The TPI AC Volt 50 is a hand held device for determining the presence or absence of AC voltage in insulated wires, wall receptacles, fuses, junction boxes, switches, and any other voltage carrying electrical system.

Robertshaw® thermopiles are the industry leader for gas appliance applications. Their primary function is to ensure a standing pilot light is operative so that on a call for heat, the main burner gas will be properly ignited. Thermopiles are placed in gas applications to detect the existence of a flame for safety purposes by shutting off the potential gas flow to a burner. A thermopile is the assembly of many thermocouples to increase the millivolt output. Robertshaw thermopiles have two types of connections: coaxial and two-wire spade connectors.

The 1950 thermopiles, also known as TP-75, are two-wire spade connectors. The 1951 thermopiles, also known as CP-2 (500-600 millivolts) are coaxial connectors.

The 1950 and 1951 Series Thermopiles (pilot generators) are designed for use on self-powered gas control systems. They can be used to replace similar competitive devices.

Features and Benefits

Stainless steel outer jacket for long life and resistance to heat blistering

RECOMMENDED FOR: high-horsepower and heavy-duty applications where durability and performance are crucial. These belts are commonly used in large facilities HVAC systems, agricultural equipment, food processing machinery and deep freeze warehouses, truck and bus accessory drives, and highway repair equipment.
FOR USE WITH: ARPM and ISO standard V-belt pulleys.

Features
Features A421 Standard model
Control Front Panel LCD:
Displays the temperature, parameters, and status and allows you to adjust the backlight intensity for ambient light conditions. Custom icons display the system and control status.
Basic and Advanced Programming Menu:
Provides two levels of parameter adjustment and control setup, allowing you to set up advanced features in one menu and easily adjust basic parameters in the other menu.
On/Off Temperature Adjustment:
Allows you to select the temperature values at which the relay turns On and Off, which automatically defines the Heating or Cooling mode of operation.
Switch-Activated Temperature Setback:
Allows you to shift the On/Off temperature by an adjustable setback value. When a user-supplied switch closes the binary input control circuit, the control operates at the defined setback temperatures.
Adjustable Anti-Short Cycle Delay:
Allows you to select the minimum time the output relay remains off before the next on cycle; avoiding short cycling, hard starts, and nuisance overload outages on compressors and other inductive applications.
Adjustable Sensor Offset:
Allows you to adjust the displayed temperature to the actual sensed temperature.
Optional Restricted Adjustment Mode:
Allows you to restrict the On/Off adjustment to your defined temperature range.
Sensor Failure Mode:
Allows you to select the relay On/Off state in the event of a sensor or sensor wire failure.
Backlight Brightness Level:
Allows you to adjust the LCD backlight intensity.
Extra Features A421 Defrost model
Off-Cycle Defrost:
Allows you to shut off the refrigeration system for defined defrost time interval and frequency. You can also start or stop a manual only defrost offcycle.
Extra Features A421 Timer model
Free-Cooling and Ventilation:
Allows you to adjust for free-cooling and timed-ventilation, and provides over-cooling protection.

The A421 Series Electronic Temperature Controls are single-stage controls with a single-pole, double-throw (SPDT) output relay. A421 Controls feature a bright backlit LCD with adjustable brightness and a three-button touchpad interface that can be set up to restrict user adjustments. An LED indicates the output relay's On/Off status. Standard A421 Series control modules have simple On and Off temperature settings for heating or cooling, an adjustable anti-short cycle delay, temperature setback, and sensor offset capability. The temperature control range is -40 to 212°F or -40 to 100°C. The A421 controls are available either in Type 1 (NEMA), IP20 (CE), high-impact plastic enclosures suitable for surface or DIN rail mounting or in Type 4X (NEMA), IP67 (CE) watertight, corrosion resistant surface mount enclosures.

The A421 Electronic Temperature Control can be used to control a wide variety of single-stage refrigeration or HVAC equipment.Sample temperature control applications can be found inside the product data sheet.
