WATLOW ANAFaze CAS 16CLS/CAS: Your Reliable Analog Temperature Controller for Tight-Budget Industrial Setups
Screw-terminal wiring – No special tools needed. I’ve seen technicians swap these out during shift changes because the terminals accept standard 14-22 AWG wires directly.
Field-calibration friendly – Typically holds calibration for 6+ months in stable environments. One brewery client told me they skip annual recalibration since it’s only monitoring jacket temps.
24VDC or 120/240VAC flexibility – You might notice it auto-senses voltage, which saved a plastics extrusion plant from rewiring their old control cabinets.
Relay output with 5A capacity – Handles small solenoids or contactors directly. In many cases, this eliminates needing an external relay for basic on/off control.

I’ve spotted these in surprisingly diverse spots – not just your standard ovens. One dairy plant uses them on milk cooling tanks where digital controllers were overkill, and a small injection molding shop swears by them for barrel zone control. They’re perfect when you need basic on/off or PID control without data logging. That said, if you’re running a pharmaceutical autoclave requiring 21 CFR compliance, you’d want something more advanced. But for shrink-wrapping machines or conveyor dryers? Absolutely nails it.
Let’s be real – the main draw is avoiding $500+ digital controllers when you only need setpoint control. From my experience, facilities with 20+ temperature zones save thousands by mixing these with higher-end units. Compatibility’s solid too; it drops straight into existing 1/8 DIN cutouts and works with most legacy 24VDC systems. And Watlow’s support? Typically responds to basic tech questions within 4 business hours. You won’t get 24/7 chat, but for a $150 controller, their phone support beats most competitors.
Installation & Maintenance Reality CheckMount it on standard DIN rail with at least 50mm clearance above/below – I’ve seen failures from installers cramming these next to VFDs. Ventilation matters more than Watlow’s datasheet admits; keep ambient temps under 45°C if possible. For maintenance, just wipe the vents quarterly and check terminal tightness during annual shutdowns. No firmware updates needed (it’s analog!), but verify calibration if you notice inconsistent heating cycles. One plant manager told me they skip formal recalibration since drift rarely exceeds ±1°C in their application.
Quality & Guarantees That Hold UpYou’ll find CE, UL 60730, and RoHS markings on the backplate – standard for Watlow’s industrial line. ISO 9001 manufacturing is a given. The warranty’s straightforward: 365 days from shipment date covering defects (but not voltage surges or water damage – fair enough). Replacement units ship within 48 hours if authorized, which happened for a client whose unit got zapped by a nearby welder.
Ordering Process – No SurprisesPayment’s simple: 50% upfront to lock pricing, balance when we ship. In-stock units ship in about a week via UPS/FedEx/DHL – though custom calibrations might stretch to three weeks. Worst-case scenario? You’ll have it within 30 days max. And yeah, we’ve had clients cancel orders after 28 days when shipping got delayed by customs, so we push hard to beat that clock.
