Decode Multispan model numbers and ordering codes — family prefixes, series numbers and build suffixes like CC 510-B1-01-W — so you order the exact part first time.
Why Multispan part numbers matter when you order
Multispan builds a broad catalogue — refrigeration controllers, PID temperature controllers, protection and motor-protection relays, timers, water-level controllers, SMPS and data loggers — and many models look similar on the label. A single wrong character can mean the difference between a relay-output and an SSR-output controller, or a 12 V and a 24 V power supply. Reading the model and ordering code correctly lets you confirm the exact device and its variant before a purchase order goes out. As the authorized Multispan distributor for the UAE and GCC, Al Misbah Al Sehri quotes against the full code so what arrives matches what your panel drawing calls for.
The anatomy of a Multispan model number
Most Multispan codes follow the same pattern: a family prefix, a series number, and an optional build suffix. Take CC 510-B1-01-W. 'CC' is the family (Cryo cooling controller), '510' is the series that fixes the core function and size, and the trailing '-B1-01-W' block specifies the build variant — sensor input, supply and housing details. Protection relays such as VPR-22U or SVR-22U use a shorter form: letters for the device type, then a number tied to the frame or range. Once you can see those three parts, almost every Multispan code becomes readable at a glance.
Family prefixes: what the letters tell you
The opening letters are the fastest way to place a part. CC denotes Cryo refrigeration/cooling controllers (CC 510, CC 520, CC 552). TC is a temperature controller and MHC/MHT cover humidity and combined humidity-temperature. On the protection side, VPR and VMR are three-phase voltage protection relays, SVR is single-phase, SPP is a single-phasing preventor and VR is a voltage relay; OLR is an overload relay and MPD a motor protection device. DI and DT are timers, WLC is a water-level controller, MS a data logger/scanner, and PS an SMPS power supply. Match the prefix first, then read the number.
Ordering codes and their build suffixes
The plain model (CC 510) identifies the product; the full ordering code (CC 510-B1-01-W, or TC 510-A2-01-W) pins down the exact build. Those suffix blocks encode variant choices such as the sensor/input type, supply voltage and housing — the reason two units with the same 510 series can differ in the field. Some codes carry a shorter suffix (CC 548-B1-01) or a trailing letter (MS 5716RU-M1, MPD-192-A2-100). Because suffix conventions vary by family and can be revised, treat the full ordering code as the definitive reference and confirm each field against the current datasheet before you commit a quantity.
What the numbers and letters commonly signal
The digits are rarely arbitrary. On modular DIN-rail devices the '22' in VPR-22U, SVR-22U, SPP-22 and DI-22 corresponds to the 22.5 mm module width. SMPS codes read directly: PS24-10A is a 24 V DC, 10 A (240 W) supply, and PS12-5A a 12 V, 5 A unit — voltage then current. DT-series timers spell out their range in the suffix (DT-10S/30S/60S in seconds, DT-15M/30M in minutes). A trailing 'U' generally marks a universal or wide-range supply, as on the DI-22U and SVR-22U. Read the number as a spec cue, then verify it on the datasheet.
CC510, CC-510 or CC 510 — same part, different typing
Buyers and search engines write these codes three ways: CC510, CC-510 and CC 510. The space and hyphen are formatting only — all three point to the same physical controller, so don't let punctuation make you think you've found a different variant. The genuine distinction always lives in the ordering-code suffix, not in whether a dash is present. When you search or email an enquiry, any format works; our product pages list each model 'also searched as' all three spellings so the right part surfaces however you type it.
Confirming the exact part before you buy
To be certain, quote the full ordering code and cross-check the load-bearing fields — sensor/input, supply voltage, output type (relay vs SSR) and mounting. If you only have a plain model number or a photo of the faceplate, that is usually enough to identify the family and series; the distributor can then confirm the correct suffix and current equivalent.
